The novel has no season. The novel only has one ending and it is a happy one, unless the producer somehow wants to change it to a tragic one. In that case, I will curse them for hurting Tee.
clarify what I meant. The novel is confirmed to have a happy ending. The series is based on the novel but we don't know season 1 will stop at which part in the novel. The producer may choose a neutral or sad part of the novel to end season 1 to keep us hang in there until next year.
